a tiny finger of Cahorra Bassa lake......The Cahora Bassa lake is Africa's fourth-largest artificial lake, situated in the Tete Province in Mozambique. The name Cabora Bassa is an earlier misspelling of the name. In Africa, only Lake Volta in Ghana, Lake Kariba, on the Zambezi upstream of Cahora Bassa, and Egypt's Lake Nasser are bigger in terms of surface water. Most of the electricity generated by Cahora Bassa, which is located on the Zambezi River in western Mozambique, is sold to nearby South Africa. .It is widely believed that there is a breeding colony of Zambezi Shark "trapped" inside the dam. As the Bull Shark is known to travel >100 km upstream, this phenomenon does not conflict with existing scientific and biological fact. In particular an ocean-dwelling species, bull sharks are perfectly capable of living in fresh water for their entire lifespan. Local tribes have indeed reported sightings (and attacks) by this isolated community of shark, although these have yet to be substantiated with hard evidence.
